Abstract (en)
[origin: ES482671A1] A sealed can or similar container having a can body the wall of which is internally lined with a coating is sealed with a deep-drawn membrane in a manner which leaves on the inside of the can wall surrounding a can top opening an annular zone uncovered by said membrane, but with the coating of the can wall intact, which annular zone extends between a lower internal edge of a rim-covering part of the membrane and the upper edge of a collar part of the membrane, which collar part is integral with, and extends upwardly from and surrounds a flat part of the membrane which covers the said can opening, and which collar part is glued or welded to the inside of the can wall beneath said uncovered zone. A preformed closure element destined for sealing fastening in a can opening, a process and apparatus for producing a rupturing zone in which preformed closure element, and a process and apparatus for manufacturing a sealed can with the aid of the preformed closure element are also described.
